Associated Workspaces grid
The Associated Workspaces grid shows all the geodatabases that this feature class is associated to. This grid is read-only. To associate/disassociate a feature class right-click on the replica geodatabase node and select the appropriate tool. Replica feature classes can also be disassociated by right-clicking on the replica feature class node.
Default Workspaces
Each feature class is required to have a default workspace connection. The default workspace for a feature class is the geodatabase it is associated to that is not a replica workspace.
Note: A feature class is not able to be associated to more than one non-replica geodatabase.
